Toall whom it may concern:

Be-it known that LEMIL J. CARROLL, a citizen of the United States,residing at Norwood, in the county of Hamilton and State of Ohio haveinvented certain new and useful improvements in Electrical Heating Meansfor Collar Shapers, of which the following is a specification.

J This invention relates to collar shapers and particularly to theheating means therefor.

The object of the invention is to provide improved electrical meansforheating the ironing member, and particularly electrical heating means inwhich the heat is generated by induction. Further objects of theinvention are in part obvious and in part will appear more in detailhereinafter. V f

Referring to the drawings, Fig. 1 repre-' sents a sectional elevation ofone form of collar shaper embodying the invention; Fig. 2 is a sectionalplan view on the line 22, Fig. 1; Fig. 3 is a detail sectionalelevationon the line 3 -3, Fig'. 2; Fig. 4 is adetail longitudinalsection, showing the primary coil, core, secondary ring and the'lines ofmagneticfiux; and Flg. 5 is a detailsectional' elevation, correspondingto Fig. 1 and'illustrating'a modificatio So fares the present inventionis concerned, to wit, the construction and opera tion of the heatingmeans, the particular arrangement of the collar 'shaper itself isimmaterial. Indeed, the inventionmaybe applied to other forms of ironingmachine than collar shapers and ma be used for heatin any one or more 0cooperatively relate relatively movable ironin or press ing members. Forpurposes of i lustration,

however, the drawings show a collar shaper of the general constructionand arrangement shown, described and claimed in the two Patents,1,397,303, granted Nov. 15, 1921, and 1,433,316, granted Oct 24, 1922 ofwhich the inventor-is CharlesE. Warea1n, to which reference may be hadfor a more 1 complete description thereof. So' far asdescription isnecessary for v the purposes of this application, the collar sha'percomprises"- a base or body 1 adapted for attachment to asuitablesupport, such asa table or shelf, and having a depending tubularportion 2 in which slides a vsleeve 3 carried by the- 66' base- 4 of acollar mold 5 provided with a I on which the ironing member 13 turns. v

stop screw 6 passing through an openin in the base 1. The collar mold isnormally I pressed upwardly by a compression spring 7 surrounding acentral tube 8 which rotates in'the sleeve 2 and a bushing 9.adj ustablythreaded into the'upper end of the sleeve 3 for adjusting the springpressure. The central tube 8 supports a [hollow I T-shaped member 10whose opposite ends serve as trunnions to carry a bracket member 11 towluch are pivoted on a horizontal axis the side arms 12 of an ironingshoe or member 13 having the usual ironing groove or recess cooperatingwith the mold 5. Between ears 14 of the bracket 11 is ivoted a lockingmember, one arm 15 of w ich is adapted in depressed position of the ironto engage thev upper inner corner of the ironing member to lock the samein its depressed position. The upper arm 16 of said locking member isconnected by a link 17 to an arm 18 carried by" the operating arm orhandle 19 pivoted at 20 to brackets on the front of the ironing member13 and provided with two abutments 21, 22. The ironing'member 13 has adepending portion 23adapted to engage a, fixed stop 24 on thebracket11,v and the inner surface 25 of said ironing member is preferablycurved on an are around the axis Fig. 1 shows the parts in ironingosition. In this position the handle 19 has been depressed until theironing member 13 has engaged the stop 24 and the collar-mold 5, and hasdepressedthe latter against the spring 7. In this position the iron canbe swung around on a collar to iron the samebut without liability ofincreasing the iron+ ing pressure, due to the absence of verticalmovement of the hollow post 8 and the abutment of .the iron. against thestop 24. If

the handle 19 is elevated the first motion of said handle turns the samerelative to the iron until the abutment 22 strikes the iron.-

. The heating means includes a primer.

coil 26which surrounds a suitable core, suc as the forward exten'dedportion of the hollow member 10, the wires 27 for said coil passing intosaid tube and through-the vertical tube-8 to asuitable switch 28.Associated with the coil 26 and its central core the ironing member 13and is secured there in by a retaining plate secured to the iron by ascrew 31.

When current is caused to flow through the wires 27 and coil 26 saidcoil produces a magnetic field, the lines of flux in which areconcentrated by the core, as shown in dotted lines, Fig. 4. Thismagnetic field,

or at least the concentrated portion thereof includes the ring 29, evenif said ring is in its upper position due to release of the iron-' ingmember from the collar mold 5. The magnetic flux of the primary coilinduces current in the secondary member 29, the flow'or effect of thiscurrent being the production-of heat in the secondary sufficient tomaintain the ironing member 13 at proper ironing temperature. i

'In the modification shown in Fig. 5 the hollow T-shaped member 10carries a separate inner tubular member 32 provided with an end head 33fitting a recess in a heating member 34:, and in whichrecess is locatedthe secondary 29*, said secondary being secured in place by the screw 35which secures the heating member 34 to the head 33. The outer surface ofmember 34 is curved to conform to the curvature of the inner face of theironing member 13*, and heating member 34 is held in contact with saidironing member by the compression spring 36. The primary coil 26surrounds the tube 32, which serves as the core, and

is wired in the same manneras in the form shown in Fig. 1. In thisarrangement the heat is producedby induction in the heated member 34 andis transmitted by conduction resistance coil.
